Pos. traction.

Could you think of anything that would cause this? I dont know for a fact that the tires are spinning either when its doing this.
ps Ive not had it tuned yet. So at the same time this is happening the car starts busting out like its hitting the rev limiter but its only doing this when its hitting like 10-11psi and thats before 9000rpm were the limiter is. I hope Im making since.

9k on a LS?! What valvetrain?

9k on a LS?! What valvetrain?

I was wrong. When I had it tuned the first time the guys had it at 8200rpm. Stock valvetrain brand new head with 2600 mile on it.
